Choose this level (Advanced: Grade 3) if you can tackle ‘ups and downs’ competently, manage a controlled snowplough descent, and if you want to ski at a lively pace. You should also be able to get up swiftly and easily by yourself after a fall. The mix of track and off-track skiing varies.
However, for Grade 4, be prepared for long, steep ascents and descents, and for off-track skiing over variable snow. You need good fitness, stamina and sound and controlled technique. Climbing skins will be needed on some days.
